Abstract:
There is provided an electroactive composition including: a deuterated first host material and an electroluminescent dopant material. The first host is a compound having Formula I. The compound of Formula I is deuterated. In Formula I: Ar 1 to Ar 4 are the same or different and are aryl; Q is a multivalent aryl group or where T is (CR') a , SiR 2 , S, SO 2 , PR, PO, PO 2 , BR, or R; R is the same or different at each occurrence and is an alkyl group or an ary group; R' is the same or different at each occurrence and is selected H, D, or alkyl; a is an integer from 1-6; and m is an integer from 0-6.
Abstract:
There is provided a method for preparing a deuterated aromatic compound. The method comprises (a) providing a liquid composition including an aromatic compound having aromatic hydrogens, said aromatic material being dissolved or dispersed in a first deuterated solvent; and (b) treating the liquid composition with a first acid having a pKa no greater than 1, to form a first deuterated material. The equivalent ratio of the deuterium atoms to the aromatic hydrogens is at least 2.
Abstract:
Disclosed herein are novel polymer-tethered ligands, metal complexes comprising these ligands, and the use of these complexes as chain transfer catalysts to control the molecular weight of oligomeric and polymeric materials produced in a radical polymerization process. The materials made by the processes disclosed herein have significantly reduced color, making them suitable for a wide range of color-critical end-uses, including automotive coatings.
